I'm going to be building up a Bronco II, and was wondering what is the best drivetrain combo is(Engine, Axles, Trans). I understand that its going to vary with what kind of terrain and purpose the vehicle is going to be for. With that being said, I'm aiming for the best over all terrained vehicle while still keeping in a refined budget. Lets here your suggestions on the
Engine-
Transmission(manual)-
Axles (front) (rear)-

I'd like to clear at least 35's and retain the Leaf spring rear axle and coils up front.
